Warm Audio WA-84 Omnidirectional Microphone Capsule (Black)

Warm Audio WA-84 Omni Capsule (Black): Add Omni to Your WA-84

The Warm Audio WA-84 Omnidirectional Capsule in black is an interchangeable capsule that adds a true omni polar pattern to any WA-84 small-diaphragm condenser microphone. The WA-84 is a small-diaphragm pencil condenser, and its capsules thread on and off so a single microphone can be voiced for different applications. This omni capsule expands what your WA-84 can do, opening up room recording, ambience capture, and natural close-miking that a cardioid pattern cannot provide. Swapping is as simple as unscrewing the existing capsule and threading this one in its place, with no tools and no re-cabling. For anyone who already owns a WA-84, it is the most direct way to unlock a completely different set of recording techniques. It turns one microphone into a more versatile tool.

What an Omnidirectional Pattern Does

An omnidirectional microphone captures sound equally from all directions rather than focusing on what is in front of it like a cardioid. This has two important consequences for how a recording sounds. First, an omni pattern has essentially no proximity effect, the bass boost that cardioid microphones produce as you move them close to a source, so close-miked instruments stay tonally natural. Second, an omni typically has a more even and extended frequency response with less coloration off-axis, capturing an open, true-to-life sound. That accuracy makes omni patterns a favorite for capturing the natural tone of an instrument and the ambience of the room around it. Understanding this is the key to knowing when to reach for this capsule.

Where the Omni Capsule Excels

This capsule shines wherever a natural, open, and accurate sound is the goal. On a grand piano, an omni captures the full body and resonance of the instrument without the low-end exaggeration a close cardioid would add. In room and ambience work, omni microphones gather the space and reflections that give a recording depth and dimension. For close-miking large acoustic sources, the lack of proximity effect keeps the tone balanced even at short distances. A pair of these capsules on two WA-84 bodies also opens up spaced-pair stereo and immersive recording techniques. Whenever the aim is realism rather than isolation, the omni capsule is the right choice. It complements the cardioid capsule that ships with the microphone.

A Simple, Well-Made Upgrade

This omni capsule is engineered to the same standard as the WA-84 microphone it fits, so it maintains the mic's smooth, natural character with the new pattern. Because it is passive and threads directly onto the microphone body, it draws its power from the host microphone and requires no separate supply or wiring. The black finish is matched to black-finish WA-84 bodies for a clean, consistent look. It stores safely in its protective case when not in use, ready for the next session. For a WA-84 owner, it is an inexpensive way to double the microphone's usefulness. It is the kind of accessory that quietly expands what your studio can capture.
